Information security standards

From Wikipedia, the free encyclopedia

Information security standards (also cyber security standards[1]) are techniques generally outlined in published materials that attempt to protect a user's or organization's cyber environment.[2] This environment includes users themselves, networks, devices, all software, processes, information in storage or transit, applications, services, and systems that can be connected directly or indirectly to networks.

The principal objective is to reduce the risks, including preventing or mitigating cyber-attacks. These published materials comprise tools, policies, security concepts, security safeguards, guidelines, risk management approaches, actions, training, best practices, assurance, and technologies.

History

[edit]

Cybersecurity standards have existed over several decades as users and providers have collaborated in many domestic and international forums to effect the necessary capabilities, policies, and practices – generally emerging from work at the Stanford Consortium for Research on Information Security and Policy in the 1990s.[3]

A 2016 US security framework adoption study reported that 70% of the surveyed organizations use the NIST Cybersecurity Framework as the most popular best practice for Information Technology (IT) computer security, but many note that it requires significant investment.[4] Cross-border, cyber-exfiltration operations by law enforcement agencies to counter international criminal activities on the dark web raise complex jurisdictional questions that remain, to some extent, unanswered.[5][6] Tensions between domestic law enforcement efforts to conduct cross-border cyber-exfiltration operations and international jurisdiction will likely continue to provide improved cybersecurity norms.[5][7]

International Standards

[edit]

The subsections below detail international standards related to cybersecurity.

ISO/IEC 27001 and 27002

[edit]
Main article: ISO/IEC 27001

ISO/IEC 27001, part of the growing ISO/IEC 27000 family of standards, is an information security management system (ISMS) standard, of which the last revision was published in October 2022 by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). Its full name is ISO/IEC 27001:2022 – Information security, cybersecurity and privacy protection - Information security management systems - Requirements.

The ISO/IEC 27001 Standard has been adopted identically as EN ISO/IEC 27001 by CEN and CENELEC.[8]

ISO/IEC 27001 formally specifies a management system to bring information security under explicit management control.

ISO/IEC 27002 incorporates part 1 of the BS 7799 good security management practice standard. The latest version of BS 7799 is BS 7799-3. Sometimes, ISO/IEC 27002 is referred to as ISO 17799 or BS 7799 part 1, and sometimes it refers to part 1 and part 7. BS 7799 part 1 provides an outline or good practice guide for cybersecurity management, whereas BS 7799 part 2 and ISO/IEC 27001 are normative and provide a framework for certification. ISO/IEC 27002 is a high-level guide to cybersecurity. It is most beneficial as explanatory guidance for the management of an organisation to obtain certification to the ISO/IEC 27001 standard. The certification, once obtained, lasts three years. No or some intermediate audits may be carried out during the three years, depending on the auditing organisation.

ISO/IEC 27001 (ISMS) replaces BS 7799 part 2, but since it is backward compatible, any organization working toward BS 7799 part 2 can easily transition to the ISO/IEC 27001 certification process. A transitional audit is also available to make it easier once an organization is BS 7799 part 2-certified for the organization to become ISO/IEC 27001-certified. ISO/IEC 27002 provides best practice recommendations on information security management for those responsible for initiating, implementing, or maintaining information security management systems (ISMS). It states the information security systems required to implement ISO/IEC 27002 control objectives. Without ISO/IEC 27001, ISO/IEC 27002 control objectives are ineffective. In Annex A, ISO/IEC 27002 control objectives are incorporated into ISO 27001.

ISO/IEC 21827 (SSE-CMM – ISO/IEC 21827) is an International Standard based on the Systems Security Engineering Capability Maturity Model (SSE-CMM) that can measure the maturity of ISO control objectives.

ISO/IEC 15408

[edit]
Main article: Common Criteria

This standard develops what is called the “Common Criteria.” It allows many different software and hardware products to be integrated and tested in a secure way.

IEC/ISA 62443

[edit]

Main article: IEC/ISA 62443

The IEC/ISA 62443 cybersecurity standards define processes, techniques, and requirements for Industrial Automation and Control Systems (IACS). The documents in this series are developed through a collaborative relationship between the ISA99 committee and IEC TC65 WG10, applying the IEC standards creation process where all national committees involved agree upon a common standard.

All IEC 62443 standards and technical reports are organized into four general categories: General, Policies and Procedures, System, and Component.

  1. The first category includes foundational information such as concepts, models, and terminology.
  2. The second category of work products targets the Asset Owner. These address various aspects of creating and maintaining an effective IACS security program.
  3. The third category includes work products that describe system design guidelines and requirements for the secure integration of control systems. The core of this is the zone, conduit, and design model.
  4. The fourth category includes work products that describe the specific product development and technical requirements of control system products.

ISO/SAE 21434

[edit]

ISO/SAE 21434 "Road vehicles - Cybersecurity engineering" is a cybersecurity standard jointly developed by ISO and SAE working groups. It proposes cybersecurity measures for the development lifecycle of road vehicles. The standard was published in August 2021.[9]

The standard is related to the European Union (EU) regulation on cyber security that is currently being developed. In coordination with the EU, the UNECE has created a Cyber Security Management System (CSMS) certification mandatory for vehicle-type approval. This is defined in the overarching UN Regulation 155; ISO/SAE 21434 is a technical standard for automotive development which can demonstrate compliance with those regulations.

A derivative of this is in the work of UNECE WP29, which provides regulations for vehicle cybersecurity and software updates. [10]

ETSI EN 303 645

[edit]

The ETSI EN 303 645 standard provides a set of baseline requirements for security in consumer Internet of Things (IoT) devices. It contains technical controls and organizational policies for developers and manufacturers of Internet-connected consumer devices. The standard was released in June 2020[11] and is intended to complement other, more specific standards. As many consumer IoT devices handle personally identifiable information (PII), implementing the standard helps comply with the EU's General Data Protection Regulation (GDPR) in the EU.[12]

The Cybersecurity provisions in this European standard are:

  1. No universal default passwords
  2. Implement a means to manage reports of vulnerabilities
  3. Keep software updated
  4. Securely store sensitive security parameters
  5. Communicate securely
  6. Minimize exposed attack surfaces
  7. Ensure software integrity
  8. Ensure that personal data is secure
  9. Make systems resilient to outages
  10. Examine system telemetry data
  11. Make it easy for users to delete user data
  12. Make installation and maintenance of devices easy
  13. Validate input data

Conformance assessment of these baseline requirements is via the standard TS 103 701, which allows self-certification or certification by another group.[13]

National Standards

[edit]

The subsections below detail national standards and frameworks related to cybersecurity.

NERC

[edit]

An initial attempt to create information security standards for the electrical power industry was created by NERC in 2003 and was known as NERC CSS (Cyber Security Standards).[14] Subsequent to the CSS guidelines, NERC evolved and enhanced those requirements. The most widely recognized modern NERC security standard is NERC 1300, a modification/update of NERC 1200. The newest version of NERC 1300 is called CIP-002-3 through CIP-009-3 (CIP=Critical Infrastructure Protection). These standards secure bulk electric systems, although NERC has created standards in other areas. The bulk electric system standards also provide network security administration while supporting best-practice industry processes.[1]

NIST

[edit]
Main category: National Institute of Standards and Technology
  1. The NIST Cybersecurity Framework (NIST CSF) "provides a high-level taxonomy of cybersecurity outcomes and a methodology to assess and manage those outcomes." It is intended to help private sector organizations that provide critical infrastructure with guidance on how to protect it, along with relevant protections for privacy and civil liberties.[15]
  2. Special publication 800-12 provides a broad overview of computer security and control areas. It also emphasizes the importance of security controls and ways to implement them. Initially, this document was aimed at the federal government, although most practices in this document can also be applied to the private sector. Specifically, it was written for those in the federal government responsible for handling sensitive systems.[2]
  3. Special publication 800-14 describes common security principles that are used. It provides a high-level description of what should be incorporated within a computer security policy. It describes what can be done to improve existing security and how to develop a new security practice. Eight principles and fourteen practices are described within this document. [3]
  4. Special publication 800-26 provides advice on how to manage IT security - superseded by NIST SP 800-53 rev3. This document emphasizes the importance of self-assessments as well as risk assessments. [4]
  5. Special publication 800-37, updated in 2010, provides a new risk approach: "Guide for Applying the Risk Management Framework to Federal Information Systems"
  6. Special publication 800-53 rev4, "Security and Privacy Controls for Federal Information Systems and Organizations", published April 2013, updated to include updates as of January 15, 2014, specifically addresses the 194 security controls that are applied to a system to make it "more secure".
  7. Special publication 800-63-3, "Digital Identity Guidelines", Published June 2017, updated to include updates as of December 1, 2017, provides guidelines for implementing digital identity services, including identity proofing, registration, and authentication of users. [5]
  8. Special Publication 800-82, Revision 2, "Guide to Industrial Control System (ICS) Security", revised May 2015, describes how to secure multiple types of Industrial Control Systems against cyber-attacks while considering the performance, reliability, and safety requirements specific to ICS. [6]

FIPS 140

[edit]
Main article: FIPS 140

The 140 series of Federal Information Processing Standards (FIPS) are U.S. government computer security standards that specify requirements for cryptography modules. Both FIPS 140-2 and FIPS 140-3 are accepted as current and active.

NCSC Cyber Essentials

[edit]
Main article: Cyber Essentials

Cyber Essentials is a United Kingdom government information assurance scheme operated by the National Cyber Security Centre (NCSC). It encourages organizations to adopt good practices in information security. Cyber Essentials also includes an assurance framework and a simple set of security controls to protect information from threats coming from the internet.

Essential Eight

[edit]

The Australian Cyber Security Centre has developed prioritised mitigation strategies, in the form of the Strategies to Mitigate Cyber Security Incidents, to help organisations protect themselves against various cyber threats. The most effective of these mitigation strategies is called the Essential Eight.[16]

BSI IT-Grundschutz

[edit]

The Federal Office for Information Security (German: Bundesamt für Sicherheit in der Informationstechnik, abbreviated as BSI) standards are an elementary component of the IT baseline protection (German: IT-Grundschutz) methodology. They contain recommendations on methods, processes, and procedures, approaches, and measures for various aspects of information security. Users from public authorities, companies, manufacturers, or service providers can use the BSI standards to make their business processes and data more secure.[17]

  • BSI Standard 100-4 covers Business Continuity Management (BCM).
  • BSI Standard 200-1 defines general requirements for an information security management system (ISMS). It is compatible with ISO 27001 and considers recommendations of other ISO standards, such as ISO 27002.
  • BSI Standard 200-2 forms the basis of BSI's methodology for establishing a sound information security management system (ISMS). It establishes three procedures for implementing IT baseline protection.
  • BSI Standard 200-3 bundles all risk-related steps in implementing IT baseline protection.

Industry-specific Standards

[edit]

The subsections below detail cybersecurity standards and frameworks related to specific industries.

PCI DSS

[edit]
Main article: Payment Card Industry Data Security Standard

The Payment Card Industry Data Security Standard (PCI DSS) is an information security standard for organizations that handle branded credit cards from the major card schemes. The PCI Standard is mandated by the card brands but administered by the Payment Card Industry Security Standards Council. The standard was created to increase controls around cardholder data to reduce credit card fraud.

UL 2900

[edit]

UL 2900 is a series of standards published by UL. The standards include general cybersecurity requirements (UL 2900-1) as well as specific requirements for medical products (UL 2900-2-1), industrial systems (UL 2900-2-2), and security and life safety signalling systems (UL 2900-2-3).

UL 2900 requires manufacturers to describe and document the attack surface of the technologies used in their products. It requires threat modeling based on the intended use and deployment environment. The standard requires effective security measures that protect sensitive (personal) data and other assets, such as command and control data. It also requires that security vulnerabilities in the software have been eliminated, security principles, such as defense-in-depth have been followed, and the security of the software has been verified through penetration testing.

Organisations producing Standards

[edit]

The International Organization for Standardization (ISO) is an international standards organization organized as a consortium of national standards institutions from 167 countries, coordinated through a secretariat in Geneva, Switzerland. ISO is the world's largest developer of international standards. The International Electrotechnical Commission (IEC) is an international standards organization that deals with electrotechnology and cooperates closely with ISO. ISO/IEC 15443: "Information technology – Security techniques – A framework for IT security assurance", ISO/IEC 27002: "Information technology – Security techniques – Code of practice for information security management", ISO/IEC 20000: "Information technology – Service management", and ISO/IEC 27001: "Information technology – Security techniques – Information security management systems – Requirements" are of particular interest to information security professionals.

The US National Institute of Standards and Technology (NIST) is a non-regulatory federal agency within the U.S. Department of Commerce. The NIST Computer Security Division develops standards, metrics, tests, and validation programs, and it publishes standards and guidelines to increase secure IT planning, implementation, management, and operation. NIST is also the custodian of the U.S. Federal Information Processing Standard publications (FIPS).

The Internet Society is a professional membership society with over 100 organizations and over 20,000 individual members in over 180 countries. It provides leadership in addressing issues that confront the future of the Internet, and it is the organizational home for the groups responsible for Internet infrastructure standards, including the Internet Engineering Task Force (IETF) and the Internet Architecture Board (IAB). The ISOC hosts the Requests for Comments (RFCs), including the Official Internet Protocol Standards and the RFC-2196 Site Security Handbook.

The Institute of Information Security Professionals (IISP) is an independent, non-profit body governed by its members, with the principal objective of advancing the professionalism of information security practitioners and, thereby, the industry's professionalism. The institute developed the IISP Skills Framework. This framework describes the range of competencies that information security and information assurance professionals expect to perform their roles effectively. It was developed through collaboration between private and public sector organizations, world-renowned academics, and security leaders.[18]

The German Federal Office for Information Security (in German Bundesamt für Sicherheit in der Informationstechnik (BSI)) BSI-Standards 100–1 to 100-4 are a set of recommendations including "methods, processes, procedures, approaches, and measures relating to information security".[19] The BSI-Standard 100-2 IT-Grundschutz Methodology describes how information security management can be implemented and operated. The standard includes a specific guide, the IT Baseline Protection Catalogs (IT-Grundschutz Catalogs). Before 2005, the catalogs were formerly known as "IT Baseline Protection Manual". The Catalogs are documents useful for detecting and combating security-relevant weak points in the IT environment (IT cluster). As of September 2013, the collection encompasses over 4,400 pages with the introduction and catalogs. The IT-Grundschutz approach is aligned with the ISO/IEC 2700x family.

The European Telecommunications Standards Institute standardized a catalog of information security indicators headed by the Industrial Specification Group (ISG) ISI.
